Application October 3, 1946, Serial No. 700,849

This invention relates to pointers or indicating fingers for use in connection with strip dials of radios or analogous instruments.

An object of the invention is to. provide a simple, inexpensive, attractive appearing pointer, which is highly visible and Will stand out conspicuously in its relation to a dial, as well as one which embodies a simple, practical means for connecting it to its operating cord.

With these and other objects inview, as may appear from the accompanying specification, the invention consists of various features of construction and combination of parts, which will be first described in connection with the accompanying drawings, showing a pointer for strip dials of a preferred form embodying the invention, and the features forming the invention will be specifically pointed out in the claims.

In the drawings:

Figure 1 is a perspective view of the improved pointer.

Figure 2 is an end elevation of the pointer.

Figure 3 is a top plane view of the pointer.

Figure 4 is a cross-section taken on the line 44 of Figure 2.

Figure 5 is a cross-section taken on the line 55 of Figure 2.

Figure 6 is a front elevation of a modified form of the pointer, and

Figure 7 is a cross section taken on the line 'I--'I of Figure 6.

Referring more particularly to the drawings the improved pointer or indicator comprises a body I which is substantially U-shaped in crosssection, providing a longitudinally extending slot 2 which receives the lower edge of a strip dial (not shown) such as used in radio or analogous instruments.

The forward side 3 of the body 1 has a recess 4 cut therein into which the lower end of the upright finger 5 extends. The finger 5 is provided with a longitudinally extending slot 6 in its front face which receives therein a strip 1 of a diiferent color, and preferably a high contrasting color to the color of the body I. The upright finger 5 is attached by a suitable adhesive to the body I and the strip 1 is likewise attached by suitable adhesive to the finger 5.

A flat extension 8 is formed upon the body I and extends at right angles rearwardly from the back side 9 and the body I. The flat extension 8 has a pair of slots l0 cut therein and extending inwardly from the outer free edge of the extension and terminating at their inner ends in rounded portions.

3 Claims. (Cl. 116-136.5)

The slots l0 permit the operating cord l2 to be attached to the pointer. As clearly shown in Figure 1 of the drawings the cord !2 extends along the under surface of the extension 5 to one of the slots l0, and then upwardly thru this slot, over the portion of the extension 8 between the slots, downwardly thru the other slot, and across the under surface of the remaining portion of the extension 8. Thus the cord will frictionally engage the extension and the pointer will move in unison with the movement of the cord.

The body I of the pointer or indicator is made of luminous material so that it will glow in darkness, and it is preferably made by the injection molding process well known in the plastic art.

The strip 1 is also of thermo-plastic material and is of a color contrasting to the color of the body I. While in the drawings the strip 1 is shown as the same length as the finger 5 it is to be understood that if desired it may be longer than the finger 5 depending on the width of the dial on which it is to be used.

If it is so desired a heavy line of contrasting color may be provided on the finger instead of the attached strip 1, and such a modification of the invention is shown in Figures 6 and 7 of the drawings.

The body I of the modified form of the invention is identical with the body I, and its front side 3 is provided with the recess 4 into which the end of the finger 20 extends. In this modified form the finger 20 does not have a longitudinal recess therein but has a heavy line 2! of a high contrasting color to the color of the finger, extending longitudinally of the center of the front face of the finger.

The pointer structure is made of any one of numerous thermo-plastic materials, so that it may be molded and its various parts connected by suitable adhesive. Also by the use of thermoplastic material an attractive pointer of any desired color Or combination of colors may be made.

It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown, but that they may be widely modified within the invention defined by the claims.

What is claimed is:

1. As a new article of manufacture, a pointer for use in connection with strip dials which comprises a main body having a longitudinally extending slot therein for receiving the edge of a strip dial, a finger carried by said body intermediate its ends and extending at right angles to the body, a laterally extending extension formed on said body, said extension provided with a pair of spaced slots extending inwardly from its outer edge for receiving an operating cord.

2. As a new article of manufacture, a pointer for use in connection with strip dials Which comprises a main body having a longitudinally extending slot therein for receiving the edge of a strip dial, a finger carried by said body intermediate its ends and extending at right angles to the body, a laterally extending extension formed on said body, said extension provided with a pair of spaced slots extending inwardly from its outer vided with a pair of surfaced slots extending infor use in connection with strip dials which com wardly from its outer free edge to receive an operating cord.
